    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 H;<!TX.zD  
    lD;'tqaC  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: V6iL5&  
    enableservice('AutomationServer', true) ~WVO  
    enableservice('AutomationServer') B7Ntk MK  
    '(@YK4_M  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 x_@i(oQ:_  
    toa-Wa{  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: <*'cf2Q$Av  
    1. 在FRED脚本编辑界面找到参考. (g/7yO(s  
    2. 找到Matlab Automation Server Type Library bggusK<  
    3. 将名字改为MLAPP U` R;P-

    t7#lsd`_  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 vTr34n

    4. 在探测面计算照度 K6\` __mLf  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2V#6q,2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C77D{@SM  
    7. 用Matlab画出照度数据 $&-5;4R'0
